Vagrant：如何在Vagrantfile中配置多个NIC？

Question

Vagrant：如何在Vagrantfile中配置多个NIC？

37

官方文档仅提供了一个IP的示例：

http://docs.vagrantup.com/v2/networking/private_network.html

Vagrant.configure("2") do |config|
  config.vm.network "private_network", ip: "192.168.50.4"
end

在谷歌上搜索后，我只找到了一个多个IP的示例：

https://groups.google.com/forum/#!topic/vagrant-up/hqtdOEjjlsw

Vagrant::Config.run do |config|
  config.vm.define :web001 do |config|
    config.vm.box = "base"
    config.vm.forward_port("http", 5000, 8881)
    config.vm.forward_port("ssh", 22, 2222)
    config.vm.host_name = "web001.example.com"
    config.vm.network("33.33.33.10")
    config.vm.network("33.33.33.20", {:adapter=>2})
  end
end

但是对我没有用...

任何帮助将不胜感激....

那个邮件列表的帖子早在Vagrant 1.1和新的配置API之前发布，因此语法不兼容。

但是你可以添加任意数量的config.vm.network调用，以下是一个简单的示例：

Vagrant.configure("2") do |config|
  config.vm.network "private_network", ip: "192.168.33.10"
  config.vm.network "private_network", ip: "192.168.33.20"
  config.vm.network "public_network", type: "dhcp", bridge: "eth0"
end

私有网络需要使用IP地址，换句话说，dhcp只适用于公共网络。另外最好设置要绑定的接口：config.vm.network "public_network", type: "dhcp", :bridge => "eth0"。 - sumid

谢谢，我改进了这个例子。 - tmatilai

@sumid -- Vagrant文档似乎与您的说法不符。除非您提到的是将private_network和bridge组合使用时存在某些问题？ - JimmidyJoo

确认以下配置语句的Vagrantfile：

$ grep '^[ ]\+config.vm.network' Vagrantfile
  config.vm.network "private_network", ip: "192.168.56.101"
  config.vm.network "public_network", bridge: "en0: Wi-Fi (Wireless)", auto_config: false
  config.vm.network "public_network", bridge: "en0: Wi-Fi (Wireless)", auto_config: false

网络接口的结果如下所示。您可以看到存在未配置但存在的IP内部接口。

如果您尝试将以下内容添加到您的Vagrantfile：

config.vm.network "private_network", auto_config: false

您会收到以下错误信息：

==> default: Destroying VM and associated drives...
/opt/vagrant/embedded/lib/ruby/2.4.0/ipaddr.rb:479:in `initialize': address family must be specified (IPAddr::AddressFamilyError)
    from /opt/vagrant/embedded/gems/2.1.5/gems/vagrant-2.1.5/plugins/providers/virtualbox/action/network.rb:263:in `new'

    from /opt/vagrant/embedded/gems/2.1.5/gems/vagrant-2.1.5/plugins/providers/virtualbox/action/network.rb:91:in `block in call'

似乎“private_network”设备需要一个IP地址。

使用Vagrant 1.6.1和Virtualbox的私有网络，您可以通过重复config.vm.network定义来创建多个私有IP地址：

# Vagrantfile API/syntax version. Don't touch unless you know what you're doing!
VAGRANTFILE_API_VERSION = "2"

Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|
  config.vm.box = "precise64"

  config.vm.network "private_network", ip: "192.168.50.4"
  config.vm.network "private_network", ip: "192.168.50.5"
  config.vm.network "private_network", ip: "192.168.50.6"
  config.vm.network "private_network", ip: "192.168.50.7"

end
